I have an 07' Street Bob w/ 14k miles and I seem to be having intermittent issues with the Idle Air Control. After longer cruising the bike tends to die when coming to a stop. I have run some Techron through the gas and cleaned the IAC a few times and it's helped but I wanted to get some thoughts on doing the crankcase breather mod so the oil isn't spraying back into the heads helping to clog up my IAC anymore. Do you think the breather mod will help with that issue?

 

I had the same issue. Cleaning didn't help. Replacing the IAC solved the problem. I don't think the breather mod would make a difference.

 

How much of a PITA is it to change out the IAC?

 

It's not a big deal to change the IAC if you're reasonably good with tools.
While you're at it you might as well do an external venting mod. It will only help in the long run.

 

Right on, thanks!

 

There is no upside to venting the hot, oxygen depleted, oily crankcase gas back in to your A/C; it makes a mess of your throttle body and A/C coating it in a black oily residue.

Venting to atmosphere; happy intake, happy engine, happy rider... but an unhappy EPA Too bad, so sad...

 

Do you have a pic of your setup? I saw a pic somewhere and cannot seem to find it now. Thanks!

 

I've changed up my external breathers quite a few times, this is by far my favorite. With external breathers if you use a filter you will need to occasionally wash it as it will slowly become oil saturated. Never any mess with this, and my throttle body and A/C are clean.

This is the kit I used: http://www.dkcustomproducts.com/Twin...-ACI-TC-BR.htm

I picked up a spare breather filter so one is always clean and ready to go. Since I took that image I added 5/16" fuel injection clamps to the 3/8" hoses to make sure it never has an unintended removal

 

Great, thats the pic I was looking for. I want to have my setup just like that, thanks!
